# Overview

> ESPHome configurations for integrating the ED1 Citilab ESP32 board with Home Assistant.

ED1 HOAS is a collection of [ESPHome](https://esphome.io) YAML configurations that turn the [ED1 Citilab](https://citilab.eu) ESP32 educational board into a fully integrated [Home Assistant](https://www.home-assistant.io/) device.

Pick a sample configuration, flash it, and your board shows up in Home Assistant with sensors, buttons, display control, and more — no custom firmware needed.

## What you get

* **Ready-to-use configurations** — message display, status dashboard, MQTT, IR blaster
* **Modular packages** — mix and match features like display, buttons, sensors, LED matrix, stepper motors
* **Both board revisions supported** — Rev 1.0 and Rev 2.3
